Single Camera Analysis.Many different TV programs music's videos are all recorded by a single camera, this is due to many different things such as it being cheaper. also this methods id used because It makes it easier to focus on a main point. having a single camera makes it easier to record there's only one point of view that is seen. This is a simple and basic way of using a camera, however it is very effective and quick.
friends has a single camera. I feel that is used very effectively, the camera is aimed on the actors speaking, as this is more of a 'comedy' program its gives the lines the actors say and the way they act more effect as the camera isn't moving and changing views making it difficult and hard to follow/understand.
